"You couldn't make up what has happened tonight. I've not been reading the papers so I've not been too bothered what people say," said the Wales international.
"All I wanted to do was make the most of the special atmosphere and the build up to the game. I've been reasonably lucky in football, playing for my country and other big clubs, but this is my best moment in the game.
"It was important at the final whistle that we didn't milk the victory. The dressing room was actually quite subdued afterwards. Well, as subdued as it can be after a win at the Nou Camp.
"This is a great result but it is only half-time. We've got to go back to Anfield for a completely different game, so as good a result as this is, there's still a long way to go.
"I take the rough with the smooth and to be honest I'm a bit gobsmacked tonight - coming here to the Nou Camp was something else. It's also my boy's 10th birthday today so it's just been really special.
"We wanted to hold them out for as long as possible but we knew it was going to be difficult. They are a top, top side and the reigning champions of Europe, but we've done a lot of work to prepare for this game and I think you could see that."
